Re: abs light stays on
I had this exact same problem, on a older bronco II. You need to get the ABS computer reset. You can either take it in or buy a computer your self. There are even packages that will allow you to use your own computer and just hook the car up to your lap top or desk top if you can get a cable long enough.
I never had mine done, because back then the computers were so expensive. I never caused a problem because it was only in the braking system. Now they are pretty cheap and there are a lot of other cool things you can do with them. You can reduce your gas requirements and set it for pulling, racing, and fuel efficency on the fly now. Just at the touch of a button.

The ABS light comes on when there is a malfuntion in the ABS system, not when the brakes are low. On a Ford you more than likely have a dirty sensor or pick up ring on the back side of the rotor. And no you do not have to change the rear drum brakes when changing your front pads but they should be inspected.
Usually you will change 2-3 sets of front pads before the rears need to be changed.
ABS is short for anti-lock braking system. This is a separate system from your hydraulic brakes. The abs light means the system has a problem and it is disabled until you fix it. The regular brakes still work as you know. Someone needs to scan the computer for ABS trouble codes and go from there.
I replaced the hub bearing assembly on drivers side twice and the light stayed on and the brakes worked fine. It was the wires (visible just above the tire on the frame) that rubbed against the frame that had shorted out. It was simply repaired and clip-stripped up out of the way. The light has been off every since then.
You had to leave something out, or you got a pad in backwards. The right front right,? it is not grabbing, just grinding, should be easy enough to spot, take the wheel off again and find the problem, Changing the pads should have nothing to do with the abs,. I don't know why the light would be coming on unless you have too much movement for the abs to work, or not enough. Check it out, hope this helps.
when your bearings start going bad two things happen first the ring gear that the abs reads the wheel speed moves to where it doesnt get a reading so that would probly be the abs light and second the flexing in the rotor will tend to colapse the brake piston leaving extra gap between the piston and the brake pad you might be able to confirm this by doing small short pumps and see if the pedal improves and it stops better i suggest replacing the bearings in pairs if you continue to drive the vehicle you run the chance of ruining the calipers hope this helps
the abs sensors are on the hub not the pads and rotors.sometimes brake dust builds up really heavy or on the magnet ring and it can not generate a pulse. there is also an ABS pump that may be bad ,and it is very expensive,over 1000 dollars.have the sensors tested first.the wheel needs to be turned and the sensor output tested with an oscilloscope or scanner.
